2 Claims.

This invention relates to improvements in devices for holding windows inthe desired raised or open position.

An object of the invention is to provide an improved adjustable devicefor holding a window sash in the desired raised or open position.

Another object of the invention is to provide an improved step by stepadjustable device for positioning in a window frame below a verticallyadjustable window sash for holding the same in the desired raised oropen position.

A further object of the invention is to provide a telescoping step bystep adjustable window sash supporting device adapted to be placedbetween the window frame and the lower surface of a window sash forpositively holding the sash at the desired open or raised position.

Another object of the invention is to provide an improved window sashsupporting device which will be highly efficient in operation, and

relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds. 1

In the accompanying drawings which part of this application,

Figure 1 is a perspective view of the improved adjustable window sashholder shown in operative position between a window frame and the lowersash therefor;

Figure 2 is a perspective view of the notched base portion of theadjustable window holding device;

Figure 3 is a perspective View of the lower end of the base portion ofthe window holding device showing the hinged base plate secured theretoin lowered position;

Figure 4 is a side elevation of the base portion of the window holdingdevice showing the step by step adjustabl upper portion in section, witha window sash shown in dotted lines being supported in open position bysaid device;

Figure 5 is a perspective view of the upper portion of the windowholding device, and

Figure 6 is a perspective view of the upper end of said upper portion ofthe window holding device, showing the sash supporting angle platepivotally attached to the upper end thereof and moved to its outermostposition.

Like characters of reference are used throughout the followingspecification and the accompanying drawings to designate correspondingparts.

In carrying out the invention, there is provided an improved window sashsupporting and holding form 31 device comprising a substantiallyrectangular vertically extending base portion or member generallydesignated by the reference numeral I, the same being formed in itsforward edge with a plurality of vertically spaced inwardly extendinglocking notches 2 having fiat seats 3 forming the base portions of saidnotches.

A pair of base supporting plates 4 and 5 are hinged at 6 and Irespectively to the opposite sides of said base member I for extendingoutwardly at the opposite sides of the lower end of said member I whenthe same is placed in position upon a window sill 8 of a window frame 9,when the device is to be used for supporting or holding a window sash I0in the desired raised position.

The U-shape top or upper channel member I I of the sash supporting andholding device is made from metal, and is open on one side, the samebeing adapted to telescope and slide upwardly and downwardly upon theclose fitting base member I, and is formed with the oppositely disposedforwardly extending parallel arms I2 and I3 adjacent its lower end. Thearms I2 and I3 are formed with the depending ears I4 which support thepin I5, upon which the double ended pawl or dog I6 is pivotally mounted.

A pin I1 is connected between the outer ends of the arms I2 and I3 andsupports one end of a coil. tensioning spring I8, whose opposit end isconnected with the pawl or dog I6 for normally urging the inner endthereof in a downward direction to seat on and engage the selected seat3 forming part of th notches 2 in the base or lower member I of thewindow holding device.

The upper edges of the parallel arms I2 and I3 are disposed inhorizontal flat position and are adapted to underlie and support thewindow sash frame I 0 when the same is in open or raised position.

A metal angle window sash supporting plate I9 is pivoted upon the pin 20to one side of the upper channel member II, and is adapted to be swungover the end of said member to underlie the bottom of the window sashframe I0 when the sash is to be supported in open position above thelimits of the sash supporting arms I2 and I3, as illustrated in Figure 1of the drawings.

In operation, the window sash will be raised to the desired height, andthe supporting and holding device placed thereunder, after which theupper channel member II will be moved upwardly until the lower surfaceof the sash frame is seated upon the parallel sash supporting arms, andthe pawl or dog I6 is engaged on the nearest adjacent seat 3 in theproper notch 2.

' the scope of the invention reefers; asih As before mentioned, theparallel'a'rms I2 and for adjustably retaining said pawl in engagementl3 will support the lower window sash in a step with the desiredshoulder, and a window sash u by step manner until the sash has beenraised 7 supporting plate pivotally supported upon the approximatelyone-half of its full or open posiforward edge of one side of saidchanneled memtion, and for supporting thesash from that point her andadapted to be swung over the top of said u t t is ul y ope e Sash W l beSeated upon channeled member to provide a supporting seat the pivotedplate l9 disposed upon the upper end for a window sash.
